| 随着Web Service组合变得越来越复杂,通过测试来保证服务质量和可靠性也变得越来越重要.将传统数据流分析方法扩展用于Web Service组合测试,提出了一种基于BPEL的Web Service组合的数据流分析测试方法.该方法基于一个测试模型:Web Service组合测试模型WSCTM,该测试模型可以捕获Web Service组合的数据流接口.采用基于服务的模型WSCTM,数据流可以从3个视点来分析:服务间、服务内和服务实现构件间.从而,Web Service组合的数据流测试可以在三层上得到实现.基于以上方法,可得到Web Service组合的定义-使用链,最终可产生满足既定测试标准以获得需求Web服务组合质量要求的测试路径. |

| Abstract: |
| As the Web Service composition becomes complex, testing to ensure their quality and reliability become crucial. This paper extends traditional data flow analysis to Web Service composition testing. A test method for BPEL-based Web Service composition based on data flow analysis is presented. The test method is based on a test model called WSCTM that captures data flow test artifacts of Web Service composition. With the considerations of the intra-activity, intra-service, and inter-service, testing for Web Service composition based on data flow analysis can be accomplished in three levels, and various flow graphs are used to describe the interaction within and between services in structure model. The def-use chains of the Web Service composition can be obtained based on above analysis method. As a result, test paths can be selected to satisfy given criteria in order to achieve a desired Web Service composition test coverage. |
